The invention discloses a vehicle tire transient vertical load calculation method and device, equipment and a storage medium, and belongs to the technical field of vehicles. The method comprises the following steps: acquiring a vehicle signal and a vehicle parameter of a target vehicle when the target vehicle runs; detecting, calculating and identifying whether wheels of the target vehicle are grounded or not; and when the wheels of the target vehicle are grounded, the transient vertical load of the tires of the target vehicle at the corresponding moment is calculated in real time according to the vehicle signals and the vehicle parameters. Based on a calculation analysis method for identifying whether the wheel is grounded or not and a tire transient vertical load calculation method which is demonstrated and deduced, tire vertical load detection which is difficult to detect, high in cost, low in precision, low in reliability, complex in calculation and poor in real-time performance in the prior art is converted into a technology which is easy to detect, high in reliability, low in cost, simple in calculation and high in real-time performance; and the capability of the vehicle for sensing the road surface in real time is developed.
